HEEL-COMPRESSING MACHINE.

SPEGIFIGAT] N forming part of Letters Patent No. 637,216, dated November 14 1899.

Application filed JanuarylS, 1897. Serial No. 619,574. (No model.)

To 00 whom it may concern:

Beit known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new 5 and useful Improvement in Heel-Compressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement on that described in the patent of Charles H. Fogg and myself, dated January 12, 1897, No. 575,040, and upon my application forimprovement in heel-compressing machines executed of even date herewith,

It comprises the employment, in connection with a heel-seat former and a movable pressure-head substantially like those of the said patent and horizontally-movable side dies like those of my said application of even date herewith, of a heel-feeding device which comprises a horizontally-movable plate movable beneath the movable side dies and having the breastblock of the die attached thereto to be movable inward and outward therewith.

In the drawings, Figure 1 is a view princi pally in vertical section of portions of the machine to which my invention relates, showing the heel-blank as fed to the side dies, but uncompressed, the side dies not having been closed thereon. Fig. 2 represents the heelblank as having been compressed and moved outward with the said plate and the breastsection of the die. Fig. 3 represents the compressed heel-blank as removed from in front of the breast-block and an uncompressed heel-blank placed thereon preparatory to the inward movement of the plate and the breastblock. Fig. 4: is a view in horizontal section taken just above the upper surface of the dies. It shows them open and the former and lower plate as moved outward to receive an uncompressed heel-blank. Fig. 5 is a view in plan of the parts represented in Fig. 4, showing the former and under plate as moved inward to feed the heel-blank and also showing the position of the side sections of the die,

their operating-slides, and the former and under plate at the completion of the compressing action.

A represents the heel-seat former. It is held suspended from a stationary cross-head, (not shown;) but, like that of the said application, it is removable therefrom that others of different sizes may be substituted.

B is a verticallymovable pressure-head. It is like the pressure-head of said application and is vertically movable, as therein specified and by substantially the same means. It has mounted upon its upper surface side dies C C, which are like those described in my said application of even date and are attached to slides which are horizontally movable to close and open the dies upon the upward and do wnward movements of the pressure-head B and as described in said application. The pressure-head Bis also provided with a cavity or space 61 below the side dies and extending forye ward and back therefrom, in which a rectangular plate D is adapted to be moved forward and backward. This plate has the flat upper surface d, which is wider and longer than the die-cavity when the side dies are closed and which acts as the bottom of the said dies for all sizes of heels. It also acts, in conjunction with the breast-block F of the die attached thereto to be'movable therewith, as a feeding device, whereby the heel-blank may be fed from in front of the dies backward between the dies, and it also serves, in connection with the breast-block, to hold the heelblank between the side sections of the die while they are closing thereon and While the pressure-head is moving the said die-sections and heel toward and from the stationary former A, and after the compression of the heel-blank the said plate may be used for withdrawing the compressed heel-blank and the breast-block from between the side dies to a forward or other position from which the compressed heel-blank may be removed and an uncompressed one substituted therefor. The breast-block may be engaged and held by the said dies when in operative relation thereto and may be released therefrom upon the opening of the side dies. The plateD and the breast-block may be moved inward by a cam-and-lever connectionand outward by a I00 s ezrigszie cam-and-spring construction similar to a cam and spring of the said patent. I,

Having thus fully described my invention, I claim and desire to secure byLettei's Patent of the United States 1. In a heel-compressing machine, the combination of the heel-seat former and closing and opening side dies, a movable plate D having a flat upper surface of relatively large area which forms the bottom of the die-cavity when in position, and extends under the surface of the dies, said plate serving to feed an unconfined, uncompressed heel-blank horizontally between the closing dies which close over said plate upon said heelblank, and means for moving the said plate, the formingdies and the heel-seat former relatively to each other, as and for the purposes described.

2. The combination in a heel-compressing machine of the closing and opening side dies carried by a pressure-head, a space beneath said dies in which a slide-plate D is adapted to be moved, a section of said slide-plate forming a bottom common to all sizes of the side dies employed, the breast-section of the die carried by said slide-plate, means for moving said slide-plate and breast-section inward and outward upon said pressurehead, the heelseat former and devices for closing the side dies as the pressure-head and slide-plate are moved upward to engage the heel with the heel-seat former, as and for the purposes described.

3. The combination in aheel-compressing machine of a heel-seat former, opening and closing dies, a slide-plate a section of which forms a common bottom for all sizes of dies which may be used, the breast-section of the said opening and closing dies being attached to said plate to be movable therewitliand which cooperates with said plate as a means for holding an uncompressed heel-blank upon it while it is being fed to a position beneath the heel seat former and in operative relation with other movable sections of the die and means for closing said dies and moving said plate, dies and former relatively in relation to each other, as and for the purposes described.
